SAND DISTRIBUTOR.

Application filed June 27, 1924.

the county of Bronx and State of New York. have invented certain new anduseful lmpmvenicnts in Sand Distributors. of which the following is a.specification.

This invention relates generally to a sand applying apparatus for use oncars or trains. the invention having more partic ular reference to thecontrol means for the discharge opening from the sandbox, and having forits object the provision of a novel and improved type of control device.

For further comprehension of the invention. and of the objects andadvantages thereof, reference will be had to the following description.and accompanying drawing. and to the appended claims in which thevarious novel features of the invention are more particularly set forth.

F ig. l of the drawing is a side view of my improved device, indicatingpart of the car in dot and dash lines.

Fig. 2 is an enlarged transverse vertical sectional view taken generallyalong the line 2-2 of Fig. 1.

Fig. 3 is an enlarged horizontal sectional view taken on the line 3-3 ofFig. 1.

Fig. is a longitudinal vertical sectional view taken on the line 4-4 ofFig. 3.

Fig. 5 is a fragmentary longitudinal vertical sectional view showing amodification.

In the drawing the reference numeral indicates a portion of the platformof an electric or other car, and 11 the sandbox located under theplatform and which may be arranged for filling in any suitable manner.Fixed as by the nuts 15 to the underside of the platform 10, anddepending therefrom are the vertical rods 16 which form crosshead guidesfor a crosshead 17 consisting of the upper and lower horizontal barswhich are rigidly united by the tubuar members 18 which freely encirclethe rods 16. Fixed to this crosshead 17 midway between the rods 16 is athrust rod 18 which extends upward through a suitable opening in theplatform 10 and has a foot to pedal 19 on its upper end. Projecting fromSerial No. 722,686.

the lower side of the crosshead 17 midway between the rods 15 are thelugs 21 to which is hinged the upper end of a. link 22 which extendsdownwardly and rea-rwardly and is connected at its other end to theforward end of the rigid stem 23 of avalve plate 241 which controls thedischarge of sand from the box 11. The valve plate projects into one endof the box and is acco1nmodated between the bottom 11 of the box and asupplementary bottom member 11 which is spaced above the main bottomjust sufficient distance to accommodate the valve plate. The parts 11and 11 are formed with discharge openings 26 and 27 while the plate 24is formed with an opening or port 28 which is normally held out of mgistry with the openings 26 and 27 by means of a pair of tension springs30which conne-ct at one end to the platform 10 and at opposite ends tothe crosshead 17. A rubber hose 31 leads downward from the bot tom ofthe box 11 toconduct the sand to a. point in front of the wheel of thecar.

To guide the valve stem 23 it has fixed to the forward end thereof thecrosspiece which engages in the channeled guide elements 36 which extendhorizontally between the lower ends of the rods 16 and the box 11. Thecrosspiece may have anti-friction rollers 37 on its ends. As will beapparent, when the pedal '19 is depressed by the motorman of the car thevertical move ment of the thrust rod 18 will be transferred by the link22 to a horizontal movement of the valve stem 23 and the valve 24,bringing the latter into position with its port 28 in registry with thedischarge openings in the bottom members of the sandbox, the springs 30returning the parts to normal position when the pedal is released. Acurved yoke 38 may connect the forward ends of the guide 86 and limitmovement of the link 22. These parts may be enclosed in and protected bya suitable housing fixed to the underside of the car platform.

In Fig. 5 I have shown a modified construction arranged to agitate thesand in the box slightly when the pedal is de Pressed. As here shown therod 16' corresponding to the rod 16 does not extend at its upper endthrough the platform 10 but into a guide element i0 under the latter.Upon this rod 16 is fixed a stepped member 41 which is adapted to beengaged by the end of a lever arm 42 fulcrumed under the platform 10 bymeans of a slot and pin connection This lever arm is adapted to beengaged and depressed by a thrust rod etl slidable in a bearing element15 and extending upward through the platform and having a pedal 46 onits upper end, a coiled tension spring 47 being connected at one end tothe arm 42 and at its other end to the platform and urging the armupward and forward. lVith this arrangement the false bottom 11" in thesandbox is dispensed with and a suitable pair of guide members areformed on the side of the box for the valve plate which latter is formedwith a number of upwardly projecting tongues or spikes spaced thereover.The parts are otherwise as previously described. When the pedal 46 isdepressed the arm d2 engages successively the various steps on the member 41 as it swings downward, there being a slight backward movement ofthe rod 1i when the arm is riding from one step to the other with. aconsequent movement of the valve and agitation of the sand in the box11. In this arrangement I have indicated the connection between thevalve stem 23 and crosshead 17 as being effected by a bell. crank lever50.

While I have illustrated and described a preferred embodiment of myinvention it is to be understood that I do not limit myself to theprecise construction herein shown, and that various changes andmodifications might be made therein without departing from the spiritand scope of the invention as defined in the appended claims.

Having thus described my invention what I claim as new and desire toprotect by Letters Patent of the United States is as follows 1. In adevice of the class described, a sandbox having a discharge mouth. ahorizontally movable plate valve controlling said mouth, a pair of fixedvertical rods, crosshead guided on said rods, a pedal attached tosaidtcrosshead, and an operative connection between said crosshead andsaid valve.
